Description
[0001] The present invention relates to a detonation connector having an electric wire mounting structure and, more particularly, to a detonation connector having an electric wire mounting structure, the detonation connector being capable of maintaining an inner connection state by fixing a double coated electric wire or a single coated electric wire, which are used as a leg line, in a state of being mounted to an opening of the detonation connector.
[0002] Each document, reference, patent application or patent cited in this text is expressly incorporated herein in their entirety by reference, which means that it should be read and considered by the reader as part of this text. That the document, reference, patent application or patent cited in this text is not repeated in this text is merely for reasons of conciseness.
[0003] The following discussion of the background to the invention is intended to facilitate an understanding of the present invention only. It should be appreciated that the discussion is not an acknowledgement or admission that any of the material referred to was published, known or part of the common general knowledge of the person skilled in the art in any jurisdiction as at the priority date of the invention.
[0004] In general, explosives are used in engineering work, such as in rock blasting for tunnelling work and in the demolition of buildings. That is, a plurality of holes, into which explosives are to be inserted, is drilled to correspond to the sections of a blasting target, i.e. the object to be blasted. After an explosive is inserted into each of the drilled holes, the explosives are connected to a blasting system. The explosives are ignited by operating the blasting system, thereby exploding the blasting target.
[0005] Such a blasting system includes a detonator serving as an igniter to ignite an explosive and a blasting device providing power necessary for the actuation of the detonator and a command signal to the detonator. Here, the detonator of the blasting system is generally implemented as an electric detonator or an electronic detonator. The electric detonator or the electronic detonator is disposed on an explosive side, and a plurality of detonators is connected to a single blasting device.
[0006] Such electric detonators or electronic detonators may have a structure in which a plurality of detonators connected to a blasting device is simultaneously activated to simultaneously detonate explosives when the blasting device transmits a command thereto, or a structure in which a plurality of detonators connected to a blasting device is set to have different delay times to be sequentially activated to thus sequentially detonate explosives.
[0007] A leg line connected to an electric detonator or an electronic detonator or a leading line connected to a blasting device is formed in a shape of peeling a sheath at an end thereof, and is connected with a leading line, a leg line, and an auxiliary leading line of another electric detonator and another electronic detonator for blasting work. In this case, in places such as a tunnel that is a humid place, a connection portion of the leg line, etc. may be exposed to ground current or leakage current, so there is a risk of a safety accident due to an explosion.
[0008] The safety accident may be a greater accident especially when an operator who installs an electric detonator or an electronic detonator in an explosive is directly in contact with a tube of the electric detonator or the electronic detonator.
[0009] Accordingly, a detonation connector has been proposed to prevent an accident that may occur when a leg line and a leading line of an electric detonator or an electronic detonator are electrically connected.
[0010] The detonation connector prevents a safety accident due to ground current or leakage current, and solves an inconvenience that an operator directly uncovers sheaths of wires and connects the wires.
[0011] As a related patent to the present disclosure, Korean Utility Model Registration No. -0410147 'Wire connector for electric detonator' (Registration Date: 24 February 2006) has been proposed.
[0012] 'Wire connector for electric detonator' includes: an insulated housing having a side with an opening through which a leg line passes; a pressing member hinge-coupled to the insulated housing at one end thereof and then rotated downwards; and an equipotential connection member, which is pressed by the pressing member when the pressing member is rotated downwards, and has a plurality of long holes for connecting a leg line corresponding to the opening, so that opposite ends of the leg line are fixed at an inside of the insulated housing.
[0013] In 'Wire connector for electric detonator', when the leg line is inserted into the long holes by downwards rotational force of the pressing member, a part of a core wire of the leg line is cut-out and the leg line is installed to be conductible to the long holes, thereby achieving equipotentiality of the leg line.
[0014] However, in 'Wire connector for electric detonator', when tagging work of charging initialisation time to a detonator by electrical connection to a logger device, and of checking abnormality in the connection between the detonator and the leg line is performed, there is an inconvenience of connecting the connector to an external terminal of the logger device in a state where an upper cover of the connector is opened and then a connecting bracket is exposed to the outside.
[0015] Further, in 'Wire connector for electric detonator', there is a problem of unstable connection between a leg line and a leading line, since the connector has a linear equipotential connection member of a single connect structure.
[0016] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and embodiments of the present invention seek to provide a detonation connector having an electric wire mounting structure, wherein tagging work that may maintain a stable inner connection state by fixing a double coated electric wire or a single coated electric wire used as a leg line in a state of being mounted to an opening of the detonation connector.

[00113] Each of the electric wire mounting grooves 110 has a 'V'-shaped guide part at an opening thereof to guide an electric wire to be mounted into the electric wire mounting groove 110. Thus, when the upper casing member 300 is closed, the leading line 20 is pressed to be easily mounted into the electric wire mounting groove 110.
[00114] The wire-connecting bracket member 100 is made of an electrically conductive material, so that the leg line 10 of the detonator or the leading line 20 and a blasting device, which are mounted to the electric wire mounting grooves 110, are electrically connected to each other.
[00115] The wire-connecting bracket member 100 is made of a material such as copper or aluminum having excellent conductivity, and may be made of any materials that can electrically connect the leg line 10 with the leading line 20.
[00116] The wire-connecting bracket member 100 is configured such that the leg line 10 is mounted to a groove on a first side of the electric wire mounting grooves 110, and the leading line 20 is mounted to a groove on a second side of the electric wire mounting grooves 110, thereby wire-connecting the leg line 10 with the leading line 20.
[00117] The leg line 10 or the leading line 20 may be embedded in various modifications using a known wire formed by coating a wire with a sheath, so a detailed description thereof will be omitted.
[00118] The leg line 10 is connected to the wire-connecting bracket member 100 by passing through the groove on the first side of the electric wire mounting grooves 110, and the leading line 20 is connected to the wire-connecting bracket member 100 by passing through the groove on the second side of the electric wire mounting grooves 110.
[00119] As the leg line 10 and the leading line 20 mounted to the different electric wire mounting grooves 110 are electrically connected to a connecting bracket, the leg line 10 and the leading line 20 are wire-connected to each other.
[00120] The leg line 10 and the leading line 20 are configured such that sheaths thereof are peeled off in a portion thereof mounted to the electric wire mounting grooves 110 to expose inner wires. Then, as the exposed inner wires of the leg line 10 and the leading line 20 are connected to the connecting bracket, the leg line 10 and the leading line 20 are wire-connected to each other through the wire-connecting bracket made of a conductive material.
[00121] The wire-connecting bracket member 100 is positioned on an upper surface of the lower casing member 200. Further, a bracket mounting part 210 is positioned on the upper surface of the lower casing member 200 for mounting and fixing of the wire-connecting bracket member 100.
[00122] The wire-connecting bracket member 100 is formed in a 'U'-shape, so that the leg line 10 and the leading line 20 are connected to the wire-connecting bracket member by double contacts, respectively.
[00123] As an example, the wire-connecting bracket member 100 has the 'U'-shape, which is formed such that a pair of brackets each having the electric wire mounting grooves 110 to which the leg line 10 or the leading line 20 is mounted are connected to each other by a connection bracket.
[00124] The leg line 10 or the leading line 20 is brought into an electrically connected state by being mounted to the electric wire mounting grooves 110 of the pair of brackets. Accordingly, the leg line 10 or the leading line 20 has the double contact structure to maintain a stable wire-connection state.
[00125] The wire-connecting bracket member 100 includes a first wire-connecting bracket part 101 and a second wire-connecting bracket part 102. The first wire-connecting bracket part 101 includes: a first leading line mounting groove 111 to which a first leading line 21 is mounted; a second leading line passing hole 116 through which a second leading line 22 passes; and a first leg line mounting groove 112 to which a leg line11 electrically connected to the first leading line 21 is mounted. The second wire-connecting bracket part 102 includes: a first leading line passing hole 115 through which the first leading line 21 passes; a second leading line mounting groove 113 to which the second leading line 22 is mounted; and a second leg line mounting groove 114 to which a second leg line 12 is mounted.
[00126] Further, the first wire-connecting bracket part 101 includes a pair of first bracket part and a first connection bracket connecting the pair offirst bracket part together, thereby forming the 'U'-shape, the pair offirst bracket part each having the first leading line mounting groove 111 to which the first leading line 21, the second leading line passing hole 116 through which the second leading line 22, and the first leg line mounting groove 112 to which the first leg line 11 electrically connected to the first leading line 21 is mounted. Accordingly, as the first leading line 21 is mounted to two first leading line mounting grooves 111, and the first leg line 11 is mounted two first leg line mounting grooves 112, the first leading line 21 and the first leg line 11 have the double contact structures.
[00127] The second wire-connecting bracket part 102 includes a pair of second bracket part and a second connection bracket connecting the pair of second bracket parts together, thereby forming the 'U'-shape, the pair of second bracket part each having the first leading line passing hole 115 through which the first leading line 21 passes, the second leading line mounting groove 113 to which the second leading line 22 is mounted, and the second leg line mounting groove 114 to which the second leg line 12 is mounted. Accordingly, as the second leading line 22 is mounted to two second leading line mounting grooves 113, and the second leg line 12 is mounted two second leg line mounting grooves 114, the second leading line 22 and the second leg line 12 have the double contact structures.
[00128] The leading line 20 includes the first leading line 21 for (+) and the second leading line 22 for (-). The leg line 10 includes the first leg line 11 for (+) that is electrically connected to the first leading line 21 for (+), that is, wire-connected thereto, through the first wire connecting bracket part 101, and the leg line 10 including the second leg line 12 for (-) that is electrically connected to the second leading line 22 for (-), that is, wire-connected thereto, through the second wire-connecting bracket part 102.
[00129] The first wire-connecting bracket part 101 and the second wire-connecting bracket part 102 are positioned parallel to each other on the upper surface of the lower casing member. The first leading line mounting groove 111 and the first leading line passing hole 115 are positioned in a straight line, and the second leading line mounting groove 113 and the second leading line passing hole 116 are positioned in a straight line.
[00130] The first leading line 21 is mounted to the first leading line mounting groove 111 and connected to the first wire-connecting bracket part 101, and then passes through the first leading line passing hole 115. Thus, the first leading line passes from a first side of the lower casing member 200 to a second side thereof in a state of being disconnected to the second wire-connecting bracket part 102 without being connected thereto.
[00131] The second leading line 22 is mounted to the second leading line mounting groove 113 to be connected to the second wire-connecting bracket part 102, and then passes through the second leading line passing hole 116. Thus, the second leading line 22 passes from the first side of the lower casing member 200 to the second side thereof in a state of being disconnected to the first wire-connecting bracket part 101 without being connected.
[00132] The lower casing member 200 is provided with lower side walls 200a protruding upwards from opposite side surfaces thereof. Each of the opposite lower side walls 200a has a first lower passing hole 200b and a second lower passing hole 200c through which the first leading line 21 and the second leading line 22 pass, respectively.
[00133] The lower casing member 200 has an opening at a front surface thereof so that the leg line 10 may be inserted into the lower casing member 200. The lower casing member 200 has a leg line mounting part 250 therein, the leg line mounting part 250 is connected with the opening of the lower casing member 200 and is provided to fix the inserted leg line in a mounted state.
[00134] The leg line mounting part 250 is positioned in a straight line at the centre of the lower casing member 200 in a longitudinal direction thereof, so that the leg line 10 may be positioned in the straight line between the first wire-connecting bracket part 101 and the second wire-connecting bracket part 102.
[00135] The leg line mounting part 250 is a passage open toward the front of the lower casing member 200. When the leg line 10 is inserted into the lower casing member 200, and then is mounted to the leg line mounting grooves 112 and 114 of the wire-connecting bracket member 100, the leg line 10 is wire-connected with the leading line 20 through the wire connecting bracket member 100.
[00136] In detail, the first leg line 11 is mounted to the first leg line mounting groove 112 of the first wire-connecting bracket part 101 by passing through the leg line mounting part 250, so that the first leg line 11 is wire-connected with the first leading line 21. The second leg line 12 is mounted to the second leg line mounting groove 114 of the second wire-connecting bracket part 102, so that the second leg line 12 is wire-connected with the second leading line 22.
[00137] The first lower passing hole 200b and the second lower passing hole 200c are positioned perpendicular to the leg line mounting part 250.
[00138] The first lower passing hole 200b and the second lower passing hole 200c have open upper portions to allow the first leading line 21 and the second leading line 22 to be inserted into the lower casing member through the open upper portions thereof. Accordingly, the first leading line 21 and the second leading line 22 are pressed by the upper casing member 300 so that the first wire-connecting bracket part 101 is coupled to the first leading line 21 and the second leading line 22 and the second wire-connecting bracket part 102 is coupled to the first leading line 21 and the second leading line 22.
[00139] The bracket mounting part 210 includes a first bracket mounting part 211 and a second bracket mounting part 212. The first bracket mounting part 211 is provided to be coupled to the first wire-connecting bracket part 101 and second bracket mounting part 212 is coupled to the second wire-connecting bracket part 102.
[00140] As an example, the first bracket mounting part 211 and the second bracket mounting part 212 have 'U'-shapes corresponding to the shapes of the first wire-connecting bracket part 101 and the second wire-connecting bracket part 102.
[00141] The first wire-connecting bracket part 101 and the second wire-connecting bracket part 102 are coupled to the first bracket mounting part 211 and the second bracket mounting part 212 respectively in a mounted state, and are positioned in a state of protruding on the upper surface of the lower casing member 200.
[00142] As an example, the lower side walls 200a of the lower casing member 200 protrude on the upper surface of the lower casing member 200 with having heights equal to or higher than heights of the first wire-connecting bracket part 101 and the second wire-connecting bracket part 102.
[00143] The first wire-connecting bracket part 101 and the second wire-connecting bracket part 102 are positioned between the lower side walls 200a of the lower casing member 200, the lower side walls 200a protruding upwards from the upper surface of the lower casing member 200. The first leading line mounting groove 111, the first leading line passing hole 115, and the first lower passing hole 200b of the lower side walls 200a are positioned in a straight line. The second leading line mounting groove 113, the second leading line passing hole 116, and the second lower passing hole 200c of the lower side walls 200a are positioned in a straight line.
[00144] The first leading line 21 is wired by passing through the first leading line mounting groove 111, the first leading line passing hole 115, and the first lower passing hole 200b of the lower side walls 200a that are positioned in the straight line. The second leading line 22 is wired by passing through the second leading line mounting groove 113, the second leading line passing hole 116, and the second lower passing hole 200c of the lower side walls 200a.
[00145] The first leg line 11 is wired by being inserted into the lower casing member 200 through the leg line mounting part 250 and then being bent to be mounted to the first leg line mounting groove 112 of the first wire-connecting bracket member 101. The second leg line 12 is wired by being inserted into the lower casing member 200 through the leg line mounting part 250 and then being bent in an opposite direction to the first leg line 11 to be mounted to the second leg line mounting groove 114 of the second wire-connecting bracket member 102.
[00146] The inside of the lower casing member 200 is opened and closed by the upper casing member 300. The upper casing member 300 covers an open upper portion of the lower casing member 200 to protect the leading line 20 and the leg line 10 that are internally wire connected to each other from the outside environment.
[00147] The upper casing member 300 is connected to a rear surface of the lower casing member 200, and is rotated around a connected portion so as to open and close the inside of the lower casing member 200.
[00148] A casing connection hinge part 400 is provided at the rear surface of the lower casing member 200 and a rear surface of the upper casing member 300 to connect the lower casing member 200 with the upper casing member 300 in a state where the upper casing member 300 is rotatable.
[00149] Further, a casing locking part 500 is provided at a front surface of the lower casing member 200 and a front surface of the upper casing member 300 to fix a position of the closed upper casing member 300. The casing locking part 500 is configured to lock the position of the upper casing member 300 that is seated on the upper portion of the lower casing member 200 and covers the upper portion of the lower casing member 200, and to release the locking state thereof to allow the lower casing member 200 to be opened.
[00150] By the casing locking part 500, the upper casing member 300 is maintained in a state of covering the upper portion of the lower casing member 200. When the locking state of the casing locking part 500 is released, the upper casing member 300 is lifted while being rotated around the casing connection hinge part 400, and opens the inside of the lower casing member 200.
[00151] The casing locking part 500 includes a locking member 510 and a locking coupling part 520. The locking member 510 is positioned at any one side of the upper casing member 300 and the lower casing member 200, and the locking coupling part 520 is positioned at another side of the upper casing member 300 and the lower casing member 200 and is removably coupled to the locking member 510.
[00152] The locking member 510 consists of an elastic support part 511, a first locking part 512, and a push part 513, and is provided at each of opposite sides of the upper casing member 300. The elastic support part 511 has a curved form with elasticity, the first locking part 512 protrudes from an outer side surface of the elastic support part 511, and the push part 513 is positioned at an end of the elastic support part 511 and protrudes toward an upper side wall 300a of the upper casing member 300.
[00153] The locking coupling part 520 is formed for the elastic support part 511 to be inserted therein, and has a second locking part 521 protruding from an inner side surface of the locking coupling part 520, so that the first locking part 512 is elastically locked by the second locking part 521.
[00154] The locking member 510 is provided as a pair of locking members 510 at opposite sides of a front portion of the upper casing member 300. The locking coupling part 520 is provided as a pair of locking coupled parts 520 in correspondence to the locking members 510 at opposite sides of a front portion of the inside of the lower casing member 200.
[00155] When the upper casing member 300 is closed, the elastic support part 511 is inserted into the locking coupling part 520, and the first locking part 512 is positioned in a state of being locked by the second locking part 521, so that the upper casing member 300 is maintained in the closed state.
[00156] When a pair of push parts 513 protruding toward upper side walls 300a of the upper casing member 300 are pressed, the first locking part 512 is released from a state of being locked by the second locking part 521. Then, the upper casing member 300 is rotated around the casing connection hinge part 400, so that the lower casing member 200 may be opened.
[00157] Meanwhile, the upper casing member 300 is provided with a wire-connecting press part 310 at a lower surface thereof. The wire-connecting press part 310 presses the leg line 10 or the leading line 20 to insert the leg line 10 or the leading line 20 into the electric wire mounting grooves 110, so that the leg line 10 or the leading line 20 is wire-connected to the wire-connecting bracket member 100.
[00158] The wire-connecting press part 310 presses the leg line 10 or the leading line 20 to allow the leg line 10 or the leading line 20 to be mounted to the electric wire mounting grooves 110. Thus, as a sheath of the leg line 10 or the leading line 20 is peeled off inside the electric wire mounting grooves 110 the leg line 10 or the leading line 20 may be electrically connected, that is, wire-connected, to the wire-connecting bracket member 100.
[00159] The electric wire mounting grooves 110 is formed with a width equal to or less than a diameter of a wire in a form of peeling a sheath from the leg line 10 or the leading line 20. When the leg line 10 or the leading line 20 is mounted to the electric wire mounting grooves 110, the leg line 10 or the leading line 20 may be mounted to the electric wire mounting grooves 110 while a sheath thereof is removed.
[00160] The leg line 10 or the leading line 20 is pressed by the wire-connecting press part 310 from a state of placed on openings of the electric wire mounting grooves 110, that is, the 'V'-shaped guide part thereof, and then is mounted to the electric wire mounting grooves 110. At this time, a sheath of the leg line 10 or the leading line 20 is peeled off only at a portion mounted to the electric wire mounting grooves 110, so that the leg line 10 or the leading line is electrically connected to the wire-connecting bracket member 100, that is, wire-connected thereto.
[00161] The wire-connecting press part 310 has a bracket insertion part 311, so that the wire-connecting bracket member 100 protrudes from the upper surface of the lower casing member 200 is partially inserted into the wire-connecting press part 310 when the upper casing member 300 is closed.
[00162] When the upper casing member 300 is closed, as the wire-connecting bracket member 100 is inserted into the bracket insertion part 311, the wire-connecting press part 310 presses the leg line 10 or the leading line 20 placed on the 'V'-shaped guide part of the electric wire mounting grooves 110. Thus, the leg line 10 or the leading line 20 may be mounted to the electric wire mounting grooves 110.
[00163] When the upper casing member 300 is closed, the wire-connecting press part 310 presses the leg line 10 or the leading line 20 inside the lower casing member 200. Thus, a position of the leg line 10 or the leading line 20 may befirmly fixed.
[00164] The wire-connecting press part 310 may have a first leading line pressing groove 311c and a second leading line pressing groove 311d at an upper portion thereof. The first leading line pressing groove 311c is positioned in a straight line with the first leading line mounting groove 111, the first leading line passing hole 115, and the first lower passing hole 200b of lower side walls 200a. The second leading line pressing groove 31Id is positioned in a straight line with the second leading line mounting groove 113, the second leading line passing hole 116, and the second lower passing hole 200c of the lower side walls 200a.
[00165] The bracket insertion part 311 has a pair offirst bracket insertion parts 311a in which the pair of first brackets of the first wire-connecting bracket part 101 is inserted, and a pair of second bracket insertion parts 31lb in which the pair of second brackets of the second wire-connecting bracket part 102 is inserted.
[00166] As an example, the first leading line pressing groove 311c and the second leading line pressing groove 311d are positioned in a straight line on a lower surface of the wire connecting press part 310, the lower surface excluding the first bracket insertion parts 311a and the second bracket insertion parts 311b.
[00167] The upper casing member 300 is provided with the upper side walls 300a protruding from opposite sides thereof, the upper side walls 300a partially overlapping the lower side walls.
[00168] The upper side walls 300a are positioned to partially overlap the lower side walls 200a in contact with outer side surfaces of the lower side walls 200a, when the upper casing member 300 is closed. At this time, the wire-connecting bracket member 100 is precisely inserted into the bracket insertion part 311, so that the leg line 10 or the leading line 20 is pressed by the wire-connecting press part 310 so as to be wire-connected to the wire connecting bracket member.
[00169] A first side wall insertion part 300b is positioned between the wire-connecting press part 310 and the upper side wall 300a, so that an upper portion of each of the lower side walls 200a is partially inserted into the first side wall insertion part 300b. A second side wall insertion part 240 is positioned at the outside of the lower side wall 200a, so that the upper side wall 300a is inserted into the second side wall insertion part 240.
[00170] The second side wall insertion part 240 positioned at the outer side surface of the lower side wall 200a has a form of being engaged with the upper side wall 300a. The upper side wall 300a is coupled to the second side wall insertion part 240 by being supported at a front end and a rear end thereof by the second side wall insertion part 240.
[00171] The upper side walls 300a have a first upper passing hole 320 and a second upper passing hole 330. The first upper passing hole 320 is open at a lower portion thereof to be connected to the first lower passing hole 200b, and the second upper passing hole 330 is open at a lower portion thereof to be connected to the second lower passing hole 200c.
[00172] A first leading line partitioning part 321 is provided at the centre of the first upper passing hole 320 to partition a space through which the first leading line 21 passes, and a second leading line partitioning part 331 is provided at the centre of the second upper passing hole 330 to partition a space through which the second leading line 22 passes.
[00173] The first leading line partitioning part 321 divides the first upper passing hole 320 into two spaces through which the first leading line 21 and the second leading line 22 pass, respectively. The second leading line partitioning part 331 divides the second upper passing hole 330 into two spaces through which the first leading line 21 and the second leading line 22 pass, respectively.
[00174] That is, the first leading line 21 and the second leading line 22 may select any one of the first upper passing hole 320 and the second upper passing hole 330 to pass through the selected hole.
[00175] The first upper passing hole 320 is divided into the two spaces, so that the first leading line 21 and the second leading line 22 may respectively and separately pass through the two spaces. The second upper passing hole 330 is divided into the two spaces, so that the first leading line 21 and the second leading line 22 may respectively and separately pass through the two spaces.
[00176] When the upper casing member 300 is closed by being rotated around the casing connection hinge part 400, a part of the upper portion of the lower side walls 200a is inserted into the first side wall insertion part 300b and upper side walls 300a is engaged with the second side wall insertion part 240. Accordingly, the wire-connecting bracket member 100 may be precisely inserted into the bracket insertion part 311.
[00177] The first leading line 21 is fixed in a state of being pressed between the first lower passing hole 200b and the first upper passing hole 320, thereby minimising damage thereof due to bending. The second leading line 22 is fixed in a state of being pressed between the second lower passing hole 200c and the second upper passing hole 330, thereby minimising damage thereof due to bending.
[00178] The first leading line 21 and the second leading line 22 are fixed by being fitted between the upper side walls 300a and the lower side walls 200a at opposite sides of each of the upper casing member 300 and the lower casing member 200. Accordingly, positions of the first leading line 21 and the second leading line 22 may be stably fixed, and thus connection states between the first and second leading lines 21 and the wire-connecting bracket member 100 may be stably maintained.
[00179] The first wire-connecting bracket part 101 may be configured such that, the first leading line mounting groove 111 is positioned in correspondence to the first lower passing hole 200b and the first upper passing hole 320, and the second leading line passing hole 116 is positioned in correspondence to the second lower passing hole 200c and the second upper passing hole 330.
[00180] The second wire-connecting bracket part 102 may be configured such that, the first leading line passing hole 115 is positioned in correspondence to the first lower passing hole 200b and the first upper passing hole 320, and the second leading line mounting groove 113 is positioned in correspondence to the second lower passing hole 200c and the second upper passing hole 330.
[00181] Accordingly, the first leading line 21 and the second leading line 22 may be wired to pass through the first lower passing hole 200b and the first upper passing hole 320, or to pass through the second lower passing hole 200c and the second upper passing hole 330.
[00182] When the upper casing member 300 is closed, the wire-connecting bracket is precisely inserted into the bracket insertion part 311. Thus, the wire-connecting press part 310 presses the leg line 10 or the leading line 20 positioned at the openings of the electric wire mounting grooves 110 to couple the leg line 10 or the leading line 20 with the electric wire mounting grooves 110, thereby stably wire-connecting the leg line 10 and the leading line 20 to the wire-connecting bracket member 100.
[00183] Meanwhile, the casing connection hinge part 400 may be folded and unfolded multiple times. The casing connection hinge part 400 has a casing connection member 410 having opposite ends integrally connected to the rear surface of the lower casing member 200 and the rear surface of the upper casing member 300, respectively.
[00184] A folded portion of the casing connection member 410 serves as a rotation centre of the upper casing member 300. The upper casing member 300 is rotated around the folded portion of the casing connection member 410 to open and close the upper portion of the lower casing member 200.
[00185] The casing connection member 410 is provided as a pair of casing connection members spaced apart from each other. Further, the casing connection hinge part 400 has a casing support member 420 between the spaced casing connection members 410, the casing support member 420 maintaining the upper casing member 300 inclined backwards in an inclined state.
[00186] The upper casing member 300, which is turned over, is supported in the inclined and lifted state while an upper surface of the upper casing member 300 is not parallel to the upper surface or the lower surface of the lower casing member 200.
[00187] Only when the turned-over upper casing member 300 is pushed by a force higher than a preset force, the casing support member 420 supports the upper casing member 300, so that the upper casing member 300 is rotated toward the lower casing member 200.
[00188] Opposite ends of the casing support member 420 are respectively and integrally connected to the rear surface of the lower casing member 200 and the rear surface of the upper casing member 300. When the upper casing member 300 is rotated, the casing support member 420 has a structure in which the upper casing member is folded inwards within a preset angle range and unfolded again when departing from the preset angle range.
[00189] The casing support member 420 is provided with a curved line part that is curved inwards from the centre between the opposite sides of the casing support member 420. The curved line part has a structure in which the curved line part is curved inwards within a preset angle range of the upper casing member 300 when the upper casing member 300 is rotated, and the curved line part is unfolded again when the upper casing member 300 departs from the preset angle range.
[00190] The upper casing member 300 is rotated and turned over from a seated state on the upper portion of the lower casing member 200 after the locked state thereof is released. Then, the upper casing member 300 fully opens the lower casing member 200 to allow the leg line 10 and the leading line 20 to be positioned in the electric wire mounting grooves 110 of the wire connecting bracket member 100.
[00191] The casing connection hinge part 400 includes: a casing opening guide member 430 that protrudes rearwards from the rear surface of the lower casing member 200 and having a first opening guide surface 431 of a curved surface at a part of an outside surface thereof; and a rotation guide member 440 that protrudes from the rear surface of the upper casing member 300 in a bent shape and having a second opening guide surface 441 of a curved surface at an outside surface thereof, the second opening guide surface 441 being in contact with the first opening guide surface 431. Thus, the casing connection hinge part 400 lifts the upper casing member 300 so that an angle between the upper surface of the lower casing member 200 and the lower surface of the upper casing member 300 becomes equal to or higher than a preset angle.
[00192] An opening guide passage is formed at side surface of the lower casing member 200 to be spaced apart from the casing opening guide member 430, so that the rotation guide member 440 may pass through the passage. The rotation guide member 440 passes through the opening guide passage and then the second opening guide surface 441 is moved in contact with the first opening guide surface 431.
[00193] Curvatures of the first opening guide surface 431 and the second opening guide surface 441 are different from each other, so that one of the first opening guide surface 431 and the second opening guide surface 441 pushes the other to rotate the upper casing member 300.
[00194] That is, the casing opening guide member 430 and the rotation guide member 440 are in contact with each other by the first opening guide surface 431 and the second opening guide surface 441 that have elasticity to allow the upper casing member 300 to be automatically opened and closed again. When the upper casing member 300 is closed, a state where one of the first opening guide surface 431 and the second opening guide surface 441 presses the other one to be elastically supported is maintained. When the locking state of the casing locking part 500 is released, the elastically supported state between the casing opening guide member 430 and the rotation guide member 440 is released and the upper casing member 300 is lifted to the preset angle.
[00195] Meanwhile, the lower casing member 200 or the upper casing member 300 has a tagging exposure part 220 exposing a part of the wire-connecting bracket member 100.
[00196] The tagging exposure part 220 exposes a part of the wire-connecting bracket member 100 to allow the wire-connecting bracket member 100 wire-connecting the leg line 10 with the leading line 20 to be electrically connected with a tagging logger equipment 30 without opening the upper casing member 300.
[00197] The tagging exposure part 220 includes a first exposure part 221 and a second exposure part 222. The first exposure part 221 exposes the first wire-connecting bracket part 101 that binds the first leading line 21 and the first leg line 11, and the second exposure part 222 exposes the second wire-connecting bracket part 102 that binds the second leading line 22 and the second leg line 12.
[00198] As an example, the tagging exposure part 220 is positioned in a bottom surface of the lower casing member 200 and exposes a part of the wire-connecting bracket member 100.
[00199] When the tagging exposure part 220 is positioned in the upper surface of the upper casing member 300, the leading line 20 or the leg line 10 that are wire-connected by the wire connecting bracket member 100 is exposed to the outside, thereby being damaged depending on the outside environment.
[00200] The tagging exposure part 220 is positioned in the lower casing member 200, so that the wire-connecting bracket member 100 is partially exposed and the leg line 10 or the leading line 20 is not exposed. Accordingly, the tagging exposure part 220 may have a structure of protecting the leg line 10 or the leading line 20 from the outside environment when the upper casing member 300 is closed.
[00201] In detail, the tagging exposure part 220 is formed in a groove-shaped space, which is connected to the bracket mounting part of the lower casing member 200 at the bottom surface of the lower casing member 200, in order to expose the wire-connecting bracket member 100 mounted to the bracket mounting part. The wire-connecting bracket member 100 is positioned to protrude from a void bottom of the tagging exposure part 220 that is formed in the groove-shaped space.
[00202] The first wire-connecting bracket part 101 and the second wire-connecting bracket part 102 exposed through the first exposure part 221 and the second exposure part 222 is positioned parallel to each other, and positioned to be stably connected to tagging terminals 31 of the tagging logger equipment 30, respectively.
[00203] The wire-connecting bracket member 100 protruding through the bottom of the tagging exposure part 220 is positioned lower than the bottom surface of the lower casing member 200.
[00204] That is, the height of the wire-connecting bracket member 100 protruding from the bottom of the tagging exposure part 220 is formed lower than the depth of the tagging exposure part 220 based on the bottom surface of the lower casing member 200.
[00205] The tagging logger equipment 30 is a prior art logger device, which is configured such that the tagging terminals 31 connected to the wire-connecting bracket member 100 protrude outwards on a front end of the logger device, charging initialisation time to each detonator connected to each leg line 10 is performed in a state where the tagging terminal 31 is connected with the wire-connecting bracket member 100, the tagging work of checking for abnormalities in the connection of a detonator with the leg line 10 is performed, so a detailed description thereof will be omitted.
[00206] The tagging terminals 31 include a first tagging terminal electrically connected to the first wire-connecting bracket part 101, and a second tagging terminal electrically connected to the second wire-connecting bracket part 102.
[00207] Then, the tagging logger equipment 30 has a pair of tagging guide members 32. The tagging guide members 32 have protruding shapes, are positioned such that the tagging terminals 31 are positioned therebetween, and have inside surfaces that are supported by opposite side surfaces of the upper casing member 300 or the opposite side surfaces of the lower casing member 200.
[00208] The tagging guide members 32 have ball plungers 32a at the inside surfaces thereof. Ball insertion grooves 230 into which the ball plungers 32a are inserted are positioned in the side surfaces of the upper casing member 300 or the side surfaces of the lower casing member 200.
[00209] When the tagging guide members 32 are positioned at the opposite side surfaces of the upper casing member 300 or the opposite side surfaces of the lower casing member 200, and the ball plungers 32a are inserted into the ball insertion grooves 230, the tagging terminals 31 are inserted into the tagging exposure parts 220 and then are precisely connected with the wire-connecting bracket member 100.
[00210] As an example, are positioned at the opposite side surfaces of the lower casing member 200. As the ball plungers 32a of the tagging guide members 32 are inserted into the ball insertion grooves 230, the tagging terminals 31 for the tagging work are guided to be precisely connected to the wire-connecting bracket member 100.
[00211] According to the present disclosure, the detonation connector having an electric wire mounting structure includes connection insertion parts 600 at opposite sides of the upper casing member 300 or opposite sides of the lower casing member 200, so that the tagging guide members 32 are inserted into the connection insertion parts 600 when the upper casing member 300 is closed.
[00212] The connection insertion parts 600 are formed in depressed shapes at the opposite side surfaces of the upper casing member 300 and the opposite side surfaces of the lower casing member 200, respectively. Accordingly, as the upper casing member 300 or the lower casing member 200 is positioned between the tagging guide members 32, the tagging terminals 31 are inserted into the tagging exposure parts 220 and may be stably connected to the wire connecting bracket member 100 that is positioned inside the tagging exposure parts 220.
[00213] Meanwhile, FIG. 7 is an enlarged view showing A part in FIG. 2B; FIG. 8 is a sectional view taken along B-B' line in FIG. 2B; and FIG. 9 is a sectional view taken along C C' line in FIG. 2B.
[00214] FIG. 10 is a sectional view showing an embodiment of a leg line. FIG. 10A is a view showing an example of a double coated electric wire 40, and FIG. 1OB is a view showing an example of a single coated electric wire 50.
[00215] Referring to FIGS. 2, 7 to 9, and 10, the leg line mounting part 250 has a structure in which the double coated electric wire 40 or the single coated electric wire 50 is fixed in a state of mounted to the leg line mounting part 250.
[00216] In detail, the leg line mounting part 250 is positioned at the opening side of the lower casing member 200 and connected with the opening of the lower casing member 200. The leg line mounting part 250 includes a first electric wire mounting part 251 to which the double coated electric wire 40 is mounted, and a second electric wire mounting part 252 that is positioned in a straight line with the first electric wire mounting part 251 and fixing the single coated electric wire 50 in a state of being mounted thereto.
[00217] The leg line 10 may be the double coated electric wire 40, or may be the single coated electric wire 50.
[00218] As an example, the double coated electric wire 40 includes a first line including a first wire coated with a first sheath, a second line including a second wire coated with a second sheath, and an outer sheath coating the first and second lines.
[00219] As an example, the single coated electric wire 50 includes a first line including a first wire coated with a first sheath and a second line including a second wire coated with a second sheath.
[00220] The leg line mounting part 250 is positioned at the centre of the lower casing member 200, and allows the first leg line 11 and the second leg line 12 to be stably wired by being bent toward the first wire-connecting bracket part 101 and the second wire-connecting bracket part 102 that are respectively positioned at the opposite sides of the lower casing member 200 on the basis of the centre of the lower casing member 200.
[00221] The first electric wire mounting part 251 is formed to be partially open at an upper portion thereof in order to cover a part of the double coated electric wire 40, that is, to cover at least half of the double coated electric wire 40.
[00222] The first electric wire mounting part 251 has opposite ends with elasticity of the open upper portion thereof. Thus, the double coated electric wire 40 inserted in the first electric wire mounting part 251 is elastically pressed, so that a position of the double coated electric wire 40 is stably fixed.
[00223] The second electric wire mounting part 252 is formed to be partially open at an upper portion thereof in order to cover a part of the single coated electric wire 50, that is, to cover at least half of the single coated electric wire 50.
[00224] The second electric wire mounting part 252 has opposite ends with elasticity of the open upper portion thereof. thus, the single coated electric wire 50 inserted in the second electric wire mounting part 252 is elastically pressed, so that a position of the single coated electric wire 50 is stably fixed.
[00225] According to the present disclosure, the detonation connector having an electric wire mounting structure is provided with the first electric wire mounting part 251 in which the double coated electric wire 40 may be fixed and the second electric wire mounting part 252 in which the single coated electric wire 50 may be fixed. When the double coated electric wire 40 or the single coated electric wire 50 is used as the leg line 10, the double coated electric wire or the single coated electric wire 50 is mounted to the opening side of the lower casing member 200, and a position of the double coated electric wire 40 or the single coated electric wire 50 is firmly fixed by the first electric wire mounting part 251 or the second electric wire mounting part 252. Accordingly, the leg line 10 may maintain the stable connection with the wire-connecting bracket in a state of being fixed inside the lower casing member 200.
[00226] That is, the leg line 10 using the double coated electric wire 40 or the single coated electric wire 50 is fixed by the first electric wire mounting part 251 or the second electric wire mounting part 252 at the opening side of the lower casing member 200. Therefore, the convenience of wiring operation, that is, the operation of wire-connecting an end of the leg line to the electric wire mounting grooves 110 of the wire-connecting bracket, is improved, and the connection stability of the leg line 10 after wire-connection work is improved.
[00227] When the double coated electric wire 40 is used as the leg line 10, in order to connect the leg line 10 to the electric wire mounting grooves 110 of the wire-connecting bracket member 100 by pressure of the upper casing member 300, a part of the leg line 10 may be formed in a single coated electric wire by partially peeling off the outer sheath at an end of a inserted portion of the leg line 10 into the lower casing member 200.
[00228] That is, when the double coated electric wire 40 is used as the leg line 10, a portion of the leg line 10 where the outer sheath is not peeled off is fixed by the first electric wire mounting part 251 primarily. Secondarily, a portion of the leg line 10, which has a shape of the single coated electric wire 50 such that the outer sheath is peeled off like for connection to the wire-connecting bracket member 100, is fixed by the second electric wire mounting part 252. Accordingly, a position of the leg line 10 using the double coated electric wire 40 may be stably fixed inside the lower casing member 200.
[00229] Further, the upper casing member 300 is provided with an electric wire pressing part 340 at the lower surface thereof. The electric wire pressing part 340 presses an upper portion of the leg line 10 positioned in the leg line mounting part 250.
[00230] The electric wire pressing part 340 includes a first electric wire pressing part 341 and a second electric wire pressing part 342. The first electric wire pressing part 341 presses the double coated electric wire 40 positioned in the first electric wire mounting part 251, and the second electric wire pressing part 342 presses the single coated electric wire 50 positioned in the second electric wire mounting part 252.
[00231] The first electric wire pressing part 341 has a width that may pass through an upper open portion of the first electric wire mounting part 251. The first electric wire pressing part 341 presses the upper portion of the double coated electric wire 40 positioned in the first electric wire mounting part 251, so that a position of the double coated electric wire 40 may be stably and firmly fixed.
[00232] The second electric wire pressing part 342 has a width that may pass through an upper open portion of the second electric wire mounting part 252. The second electric wire pressing part 342 presses the upper portion of the double coated electric wire 40 positioned in the second electric wire mounting part 252, so that the position of the double coated electric wire 40 may be stably and firmly fixed.
[00233] At the front of the lower casing member 200, the opening of the lower casing member 200 is formed to be open upwards. The electric wire pressing part 340 may have a third electric wire pressing part 343, which is inserted into the lower casing member 200 and presses the upper portion of the leg line at the opening of the lower casing member 200.
[00234] The third electric wire pressing part 343 presses the leg line 10, that is, the double coated electric wire 40 or the single coated electric wire 50 at the opening of the lower casing member 200. Thus, a flow of an electric wire, that is, the leg line 10, is minimised at the opening of the lower casing member 200.
[00235] The present disclosure is configured such that the double coated electric wire or the single coated electric wire used as the leg line 10 is fixed by the opening of the lower casing member 200 in a mounted state so as to maintain a stable connection state. Accordingly, the connection stability and the connection reliability of the leg line and the leading line can be secured.
[00236] The present disclosure is configured to have the double contact structure, thereby performing the stable wire-connection of the leg line 10 and the leading line 20, so that the connection stability and the connection reliability of the leg line 10 and the leading line 20 can be secured. Further, it is possible to prevent the occurrence of large accidents due to malfunctions during wire-connection work, and to reduce the blasting delay time and the trouble shooting time that are critical issues caused by a connection problem.
[00237] The present disclosure is configured such that the upper casing member 300 or the lower casing member 200 is provided with the tagging exposure part 220 that exposes a part of the wire-connecting bracket member 100 wire-connecting the leg line 10 and the leading line 20. Accordingly, the tagging work of charging initialisation time to a detonator can be performed without opening the upper casing member 300, and the convenience and the efficiency of the tagging work can be improved.
[00238] The present disclosure is not limited to the above-described embodiments, and may be implemented as various modifications, additions and substitutions without departing from the scope and spirit of the present disclosure as disclosed in the accompanying claims, and the modifications and the like are included in the configuration of the present disclosure.
